I got on my box (debian/sid) postfix/courrier/imapd ((4.4.0-2))/mysql, and
they work well together. I accessed imap thrue squirrelmail with no problem.
I make a migration to use soft raid and kernel 2.6.28 and problem come.
(For history :)
First problem i got, is the change of eth1 and eth2, so mysql made some
problem for different access, after some modification, it was ok.
Second problem, i tried to access to my mail thrue squirrelmail and got this
ERRR: Connection dropped by IMAP server.
*Query: STATUS "INBX" (MESSAGES UNSEEN RECENT)
After searching, it seem that the problem come from imap which dont answer
enough fast. I try to connect with telnet with :
. login myacount password
. select inbox
And it take around 5mn for "select inbox" for no reason, the time was lower
before migration. The mailbox is around 250Mb and dont change before and
after migration. Actually i modify php.ini to get 600s until timeout, but
its not a solution (and seem dont work, actualy, squirrelmail run for 20mn
and nothing appear).
